I'm constantly amazed by the idea of these extinct river drives - when logs floated and sluiced down river in the spring. The sheer volume of wood and manpower (and danger) that was created is staggering - even in this industrialized age as shown here. Take it back to the 1800s and it seems otherworldy.
